An elevator accelerates upward at 1.2 m/s 2 . The acceleration of gravity is 9.8 m/s 2 . What is the upward force exerted by the floor of the elevator on a(n) 51 kg passenger? Answer in units of N. 003 (part 2 of 2) 10.0 points If the same elevator accelerates downwards with an acceleration of 1.2 m/s 2 , what is the upward force exerted by the elevator floor on

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
